Troubleshooting help: No status inquiry

I'm trying to install IIRF for the first time, and have been able to get the green arrow, and the priority is set to high so the IirfGlobal.ini is being read. I just can't get any further.

Are you supposed to set the ISAPI filter on the Default Web Site in IIS 6 as well? When I do, it's not reading the priority (* Unknown *) but it is giving a green arrow. I haven't been able to get the status inquiry to show up even with it set
in the INI file. I have set the permissions as the installation instructions said.

I tried my best to search for a solution, but came up empty.

Any help would be much much appreciated. Thanks!

EDIT: I should probably add the nothing is being written to the log files as well.
